Yellowbelly Salmon: Not Always Bad

There's also a natural aspect to this. Some salmon species, especially wild ones, can have a slightly yellowish tinge to their bellies. This is usually due to their diet, such as crustaceans or algae, which can contain pigments that influence the color of their flesh. Farmed salmon often have a more uniform color due to their controlled diet, but variations can still occur. It's possible, then, that the yellow hue is simply a natural variation in the salmon.

Check for freshness

During my detective mission, to ensure the yellowing salmon was still safe to eat, I used the old "smell test" my grandmother taught me. Fresh salmon should have a neutral, salty smell, almost like a fresh ocean breeze. If it smells too fishy or sour, it's probably ripe. I also pressed the flesh to see if it had grown back—and it did. Finally, to be safe, I cut off the yellow part and cooked it with a little lemon and dill.

Get the most out of your salmon

Here are some tips to prevent the recurring yellowing problem:

1. Proper Sealing: Make sure the salmon is sealed tightly before freezing. Vacuum sealing works wonders, but if you don't have it, use plastic wrap and then place the salmon in a freezer bag.
2. Label and date: Always mark when you frozen salmon so you can track how long it's been frozen. The USDA recommends consuming frozen fish within 3–8 months to maintain its best quality.
3. Stock rotation: If you buy salmon in large batches, try to use older fillets first, following the first-in, first-out principle.

In the end, my tawny salmon turned out quite well. I grilled it perfectly and served it with garlicky asparagus. The family didn't even notice the difference. It was still juicy, delicious, and gone in minutes.

So next time you notice a yellowish tint on your thawed salmon, don't worry! Give it a quick sniff, trim off the discolored part if necessary, and then continue preparing your favorite salmon. It's likely the same delicious, nutrient-rich fish you know and love, just with a bit of character.
